ENGINE AIR - COOLING SYSTEM
I. With air cooling, the engine structure is directly cooled by inducing air to flow over its high-temperature surfaces. They are finned to present a greater cooling surface area to the air, which in non-motor-cycle applications is forced to circulate over them by means of a powerful fan. The car engine structure is almost entirely enclosed by sheet metal ducting, which incorporates a system of baffles. A similar arrangement is used with the diesel engine. These baffles ensure that the through flow of air is properly directed over the cooling surfaces of the cylinders and cylinder heads. To maintain uniform temperatures, the air is forced to circulate around the entire circumference of each cylinder and its cylinder head, the direction of flow being along the cooling fins. These are greatest in number, consistent with providing a sufficient area of flow, on the high-temperature surfaces of the cylinder head in the region of exhaust valve. The complete system forms what is known as a plenum chamber in which the internal pressure is higher than that of the atmosphere.
Finally, the heated air is discharged from the plenum chamber to the atmosphere, or redirected to heat the car interior.
ENGINE WATER - COOLING SYSTEM
II A very simple form of engine water-cooling, known as natural or thermos phonic circulation, was used in many early motor vehicles up to the late 1930s. This type of water-cooling system consisted of the following components:
Water jacket. This was formed partly in the cylinder block and partly in the cylinder head and surrounded the cylinder walls, combustion chamber and valve ports. It was provided with a lower inlet and an upper outlet connection, the latter sometimes being called the header pipe.
III. Radiator. The purpose of the so-called radiator is to dissipate the engine heat rejected to the coolant. This it does mainly by conduction and convection. It originally consisted of an upper header tank that received the heated coolant from the engine; a matrix or core that served to disperse the down flow of coolant onto fine streams and also provided for a through flow of cooling air; and a lower collector tank from which coolant was returned to the engine jacket.
IV. Flexible connection Rubber hoses with clips were used to connect the cooling jacket header pipe to the inlet pipe of the radiator header tank and the outlet pipe of the radiator collector tank to the inlet elbow of the cooling jacket.
Other fittings. The radiator header tank was fitted with a filler cap and an overflow pipe and the collector tank with a drain itable mounting lugs were also provided at the top and bottom of the radiator.
V.. Radiator fan. In many, but not all, early thermos phonic cooling system a fan was mounted behind the radiator and driven by belt and pulleys from either the crankshaft or the camshaft. Its purpose was to assist the through flow of air normally resulting from the forward motion of the vehicle and also create an air flow when the vehicle was stationary with the engine idling.
